Chinese Journal of Primary Medicine and Pharmacy 2013;20(20):3070-3071
Objective To study the correlation of operation timing,mode and curative effects of patients with severe hypertensive cerebral hemorrhage.Methods 90 patients with hypertensive cerebral hemorrhage were collected and divided into super early treatment group (32 cases),early treatment group (29 cases),delayed treatment group (29 cases) and big bone flap craniotomy treatment group (41 cases),small bone window craniotomy operation removal group(49 cases).The therapeutic effect,neural function and mental state were observed.Results The total effective rate (93.32%,93.56%),MMSE score [(22.22 ± 2.33) points,(31.55 ± 3.68) points] of super early group and small bone window craniotomy group were significantly higher than other groups (F =6.672,5.325,all P < 0.05.x2 =6.852,7.372,all P < 0.05),CSS score [(17.92 ± 1.84) points,(17.41 ± 1.97) points],NIHSS score [(22.22 ±2.33) points,(22.53 ± 2.48) points] were significantly lower than other groups(F =5.624,6.621,all P < 0.05.F =5.458,6.171,all P < 0.05).The operation timing was positively correlated with CSS and NIHSS score,while negatively correlated with MMSE.The operation mode was negatively correlated with CSS and NIHSS score,while positively correlated with MMSE.Conclusion Early small bone window craniotomy operation therapy has the positive clinical value,it can improve the treatment efficacy and neurological function.
2.A study of measurement of facial skin color using digital camera
Journal of Practical Stomatology 2009;25(6):858-861
Objective; To evaluate the reliability and reasonability of maxillofacial skin color match using the digital camera. Methods; The stability of the experimental light source was evaluated before establishing the color measurement. 122 volunteers aged from 22 to 32 years were recorded by a Canon EOS 20D digital camera in studio environment when the light source was stable. Photographs were taken under a set exposure parameters(f/4.5,1/25 s,custom white balance,ISO 800) and saved as JPEG format. The CIE L~* a~* b~* color values were obtained from the digital images using Adobe Photoshop7.0 after color correction. All data were analyzed using SPSS 10. 0. Results;The experimental light source was stable in 21 to 70 minutes. It was suitable for color measurement during this period. The color parameters of all tested maxillofacial skin were:L~*49~66,a~*7 - 18,b~*5 -22. Conclusion;The assessment of maxillofacial skin color depend on method of measurement and instrument. The method of maxillofacial skin color matching by digital camera seems reliable.
3.Clinical curative effect of chronic heart failure treated by noninvasive positive pressure ventilation method
Chinese Journal of Primary Medicine and Pharmacy 2011;18(13):1770-1771
Objective To observe the clinical curative effect of chronic heart failure (CHF) treated by noninvasive positive pressure ventilation ( NPPV). Methods 48 cases of CHF were randomly assigned to conventional drug treatment under oxygen (control group, n = 24) and non-invasive positive pressure ventilation ( NPPV) under the conventional therapy group (observation group, n =24). The plasma N-brain natriuretic peptide( proN-BNP) and cardiac function changes in two groups before and after treatment were observed. Results The total effective rate 92% in observation group was significantly higher than 66% in control group ( x2 =3. 7851, P < 0. 05 ) ; The plasma proNBNP、respiratory rate and heart rate after treatment in two groups were lower than before treatment(t = 2.787,2.815, 2. 856,2.789,2.804,2.840,all P<0.01) ;The plasma proN-BNPand heart rate in observation group after treatment were lower than the control group(t =2.123,2.221,all P <0.05). Conclusion Noninvasive positive pressure ventilation could significantly improve heart function,reduce plasma proN-BNP and enharce curative effect.

BACKGROUND:Forceful fixation and enough blood supply in fracture site are the fundament for treating bone nonunion. OBJECTIVE:To investigate the outcome of autologous lilac bone-grafting and plate fixation in treatment of the ununited distal ulnar fracture with osseous defects. DESIGN,TIME AND SETTING:The own control study was performed at the Department of Orthopaedics,Sixth People's Hospital,Shanghai Jiao Tong University from August 2002 to May 2006. PARTICIPANTS:Of 21 cases of the ununited distal ulnar fracture with osseous defects,13 cases were induced by ulnar and radial fracture,and 8 cases were induced by ulnar fracture. There were 15 cases of open fracture and 6 cases of closed fracture of first onset. Bone defects were 1.5 cm-5.0 cm,averagely 3.1 cm. METHODS:Bone defects were filled with intercalary lilac grafts. Length and axial ray of ulna were controlled. Ulna was fixed utilizing 5-8 wells 1/3 tubular plate,reconstruction plate or locking compression plate. At least two screws were used at the distal end,and 3 or 4 screws were fixed in the proximal end,FoUow-up was conducted once per month to observe clinical appearances and radiograph in each patient. MAIN OUTCOME MEASURES:Fracture nonunion,dorsal extension and palmer flexion of wrist joint,pronation and supination of the forearm were measured. RESULTS:All 21 cases were followed up for a mean time of 14.7 months. All the patients obtained bony union,and a mean time of 4.6 months (ranged 3 to 7 months). The distal ulnar healed with < 10° of angular deformity in a coronal plane in one patient and with 15° of angulation in a sagittal plane in another one,while others (19 patients) obtained satisfactory alignment. The excellent and good rate was 90.5%. CONCLUSION:Intercalary bone-grafting with autologous lilac and secure fixation for treating the ununited distal ulnar fracture with osseous defects can reconstruct ulnar length,correct deformities,and obtain good bone healing and functional recovery.

Objective:To study the soft tissue inflammation of percutaneous implants using bacteria investigation method, so as to provide basic data for further clinical study of percutaneous implants. Methods: Implants were surgically placed into tibias of the goats. The inflammatory secretion from the peri-implant soft tissue was taken to perform bacteria test on 4, 6 and 9 weeks post-operation. Meanwhile, the soft tissue inflammatory reaction was also observed weekly. Results: 5 of the 16 implants were infected. The soft tissue showed tumefaction and ulceration 2 months post-surgery. As to bacteria investigation, the number of G.Streptococci increased when the inflammation was getting more severe. Conclusion: The extent of the soft tissue inflammation of percutaneous implants probably has positive correlation with the infection of G.Streptococci.
